Description
Technical Field
[0001] This utility model relates to the field of insulation board technology, specifically a novel large-mold built-in insulation board fixer. Background Technology
[0002] Built-in formwork refers to installing insulation boards directly inside the formwork during the formwork installation process, followed by concrete pouring. This technique is suitable for cast-in-place concrete shear wall structures with painted exterior finishes. Typically, a reinforcing mesh is fixed to the formwork, the cut insulation board is attached to the mesh, anchors are installed on the insulation board, and the anchors are secured to the mesh with wire rope. At least six anchors are required per square meter. After installation, another formwork is attached to the insulation board, and the two formwork sections are secured with through-wall bolts. Concrete is then poured between the two formwork sections.
[0003] However, the installation of insulation boards in the existing technology is inconvenient. Due to the large number of anchors required during construction and the need for binding with wire, the process is time-consuming and labor-intensive, reducing the efficiency of fixing.
[0004] Therefore, we propose a new type of large-mold built-in insulation board fixer to solve the problems mentioned above.
[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0006] The purpose of this utility model is to provide a new type of large-mold built-in insulation board fixer to solve the problems mentioned in the background art of the time-consuming and labor-intensive process of installing insulation boards and the reduced fixing efficiency in the current prior art.
[0007] To achieve the above objectives, this utility model provides a novel large-formwork built-in insulation board fixer, including a template one and a template two, and an insulation board located between the template one and the template two. The insulation board is surrounded by a concrete pouring layer, and the insulation board is fixed to the template one by the fixer.
[0008] The fastener includes pre-embedded nails and positioning posts;
[0009] The pre-embedded nail is fixedly installed on the end face of the template one, and the pre-embedded nail has an insertion hole and a locking groove located at the end of the insertion hole facing the template one;
[0010] The positioning post is fixedly installed on the end face of the insulation board. The end of the positioning post is provided with an elastic connector. The positioning post is inserted into the insertion hole. The elastic connector is provided in the locking groove. The pre-embedded nail and the positioning post are locked together by the elastic connector.
[0011] Preferably, the template includes a plate, and a steel mesh is fixedly installed on the end face of the plate;
[0012] The embedded nails are distributed in the mesh of the steel mesh frame, which is wrapped in the concrete pouring layer.
[0013] Preferably, the insertion hole is a conical hole, and the end of the positioning post inserted into the insertion hole is also conical.
[0014] Preferably, the elastic connector includes a T-shaped plate and a locking block, wherein both ends of the T-shaped plate are cylindrical structures, and the end with the smaller diameter is fixed to the positioning post;
[0015] The T-shaped plate has a T-shaped guide groove on the end face of the larger diameter end facing the positioning post;
[0016] A T-shaped block is fixedly installed on one end face of the locking block positioning post, and the T-shaped block is slidably installed in the T-shaped guide groove;
[0017] The locking block has a trapezoidal cross-section, with the inclined surface facing the connection point between the T-shaped plate and the positioning post;
[0018] The smaller diameter end of the T-shaped plate is also movably fitted with a push ring, which contacts the inclined surface of the locking block;
[0019] A spring is also fitted onto the smaller diameter end of the T-shaped plate, and the two ends of the spring are fixed to the positioning post and the push ring, respectively.
[0020] Preferably, the locking block has an arc-shaped surface on the side away from the T-shaped plate, and the arc is adapted to the socket.
[0021] Preferably, the fixture further includes a groove formed at the smaller diameter end of the T-shaped plate, a sliding rod passing through the groove, and the sliding rod being fixed to the push ring;
[0022] The fixture also includes a threaded hole formed in the positioning post, and the threaded hole communicates with the slide groove;
[0023] A locking pin is threaded into the threaded hole, and the end of the locking pin contacts the slide rod.
[0024] Compared with the prior art, the beneficial effects of this utility model are:
[0025] (1) This utility model installs pre-embedded nails on template one and positioning posts on the insulation board. The positioning posts are equipped with elastic connectors. When installing the insulation board, it is only necessary to align the insulation board with template one and ensure that the position of the positioning post can be connected with the pre-embedded nails. Pressing the insulation board will allow the positioning post to be inserted into the insertion hole, and the elastic connector will be inserted into the locking groove to fix the insulation board. Compared with the method of using wire binding in the prior art, its operation efficiency is greatly improved and it has the advantages of saving time and effort.
[0026] (2) By setting the insertion hole and the positioning post to be conical, this utility model allows for an error when the insulation board is fixed and the template is aligned. When there is a certain deviation between the center of the insertion hole and the center of the positioning post 54, the elastic connector contacts the arc surface of the insertion hole. As the operator pushes forward, the elastic connector can still be inserted from the insertion hole into the locking groove, thus reducing the requirements for operational precision and making it easier for the operator to use.
[0027] (3) This utility model sets threaded holes and locking pins on the positioning pin. After the elastic connector is inserted into the locking groove, the locking pin is screwed into the threaded hole. As the locking pin extends in, its end contacts the slide rod and generates pressure, so that the push ring presses the pre-embedded pin and the locking block together, thereby further improving the fixing effect.
[0028] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.
[0042] Example 1:
[0043] Please see Figures 1-4 A novel large-formwork built-in insulation board fixing device includes: a formwork 1 and a formwork 2, and an insulation board 4 located between the formwork 1 and the formwork 2. The insulation board 4 is surrounded by a concrete pouring layer 3. The insulation board 4 is fixed to the formwork 1 by a fixing device 5. The fixing device 5 includes a pre-embedded nail 51 and a positioning post 54. The pre-embedded nail 51 is fixedly installed on the end face of the formwork 1, and the pre-embedded nail 51 has an insertion hole 52 and a locking groove 53 located at the end of the insertion hole 52 facing the formwork 1. The positioning post 54 is fixedly installed on the end face of the insulation board 4. The end of the positioning post 54 is provided with an elastic connector 55. The positioning post 54 is inserted into the insertion hole 52, and the elastic connector 55 is located in the locking groove 53. The pre-embedded nail 51 and the positioning post 54 are locked together by the elastic connector 55.
[0044] In the above technical solution, when fixing the insulation board 4, the insulation board 4 is first adjusted to be parallel to the template 1, and then the insulation board 4 is aligned with the template 1 so that each positioning post 54 is aligned with the corresponding embedded nail 51. Then the insulation board 4 is pressed so that the elastic connector 55 and the positioning post 54 pass through the insertion hole 52 in sequence. After the elastic connector 55 passes through the insertion hole 52, it is inserted into the locking groove 53 to lock.
[0045] Therefore, the above technical solution has the advantages of being simple and convenient to operate, and is relatively time-saving and labor-saving.
[0046] Please see Figure 2 Template 1 includes a plate 11, and a steel mesh frame 12 is fixedly installed on the end face of the plate 11; pre-embedded nails 51 are distributed in the mesh of the steel mesh frame 12, and the steel mesh frame 12 is wrapped in the concrete pouring layer 3.
[0047] The insertion hole 52 is a conical hole, and the end of the positioning post 54 inserted into the insertion hole 52 is also conical. By setting the insertion hole 52 to be conical, and the diameter of the hole at the end facing the insulation board 4 is larger than that at the end away from the insulation board 4, the operator's precision requirements during assembly are lower. It is only necessary to ensure that the elastic connector 55 can contact the inner arc surface of the insertion hole 52, without requiring the positioning post 54 to be aligned with the center of the pre-embedded nail 51, thus further improving the convenience of use.
[0048] Please see Figures 5-6 The elastic connector 55 includes a T-shaped plate 551 and a locking block 553. Both ends of the T-shaped plate 551 are cylindrical, with the smaller diameter end fixed to the positioning post 54. A T-shaped guide groove 552 is formed on the end face of the T-shaped plate 551 facing the positioning post 54. A T-shaped block 556 is fixedly installed on one end face of the locking block 553, and the T-shaped block 556 is slidably installed in the T-shaped guide groove 552. The cross-section of the locking block 553 is trapezoidal. The T-shaped plate 551 is shaped with its inclined surface facing the connection point between the T-shaped plate 551 and the positioning post 54. A push ring 554 is movably sleeved at the smaller diameter end of the T-shaped plate 551, and the push ring 554 contacts the inclined surface of the locking block 553. A spring 555 is also sleeved at the smaller diameter end of the T-shaped plate 551, and the two ends of the spring 555 are fixed to the positioning post 54 and the push ring 554, respectively. The side of the locking block 553 away from the T-shaped plate 551 also has an arc-shaped surface 557, and the curvature is adapted to the insertion hole 52.
[0049] The above technical solution has the following dimensional requirements: when the locking block 553 expands to its maximum position away from the center of the T-shaped plate 551, the distance from the edge of the locking block 553 to the center of the T-shaped plate 551 is greater than the diameter of the insertion hole 52; and when the locking block 553 is fully retracted, the distance from the edge of the locking block 553 to the center of the T-shaped plate 551 is less than the diameter of the insertion hole 52.
[0050] In the above technical solution, when the locking block 553 is not inserted into the socket 52, the spring 555 exerts a certain pressure on the push ring 554, causing the push ring 554 to push the locking block 553 to expand to its maximum state. During the process of inserting the positioning pin 54 into the socket 52, the locking block 553 contacts the inner arc surface of the socket 52. During the insertion process, as the socket 52 narrows, the locking block 553 contracts. Finally, after the locking block 553 passes through the socket 52 and reaches the locking groove 53, the locking block 553 is released. Under the elastic force of the spring 555, the locking block 553 returns to the outward expansion state, and at this time the locking state is achieved.
[0051] Example 2:
[0052] Please see Figures 7-8 and combined Figure 4 In comparison, based on embodiment 1, the fixture 5 further includes a groove 56 opened at the end of the T-shaped plate 551 with a smaller diameter, a slide rod 57 passing through the groove 56, and the slide rod 57 being fixed to the push ring 554; the fixture 5 also includes a threaded hole 58 opened in the positioning post 54, and the threaded hole 58 is connected to the groove 56; a locking pin 59 is threadedly connected to the threaded hole 58, and the end of the locking pin 59 is in contact with the slide rod 57.
[0053] Since there is some instability after installation by pressing with spring 555, in order to prevent the insulation board 4 from loosening, the sliding rod 57 is pressed with locking nail 59 to improve stability.
[0054] Furthermore, the insulation board 4 also has holes that are concentric with the threaded hole 58. The locking pin 59 passes through the insulation board 4 and the threaded hole 58, which can further improve the installation stability.
[0055] Working principle: Adjust the insulation board 4 to be parallel to the template 1 and align the insulation board 4 with the template 1 to ensure that the position of the positioning post 54 can be connected with the pre-embedded nail 51. Press the insulation board 4 so that the positioning post 54 is inserted into the insertion hole 52 of the pre-embedded nail 51. After the positioning post 54 is inserted into the insertion hole 52, the elastic connector 55 is finally locked into the locking groove 53, thereby locking the pre-embedded nail 51 and the positioning post 54.
[0056] After the elastic connector is inserted into the locking groove 53, the locking pin 59 is screwed in. The end of the locking pin 59 contacts the slide bar 57 and generates pressure, causing the push ring 554 to press the pre-embedded pin 51 and the locking block 553 together, further improving the fixing effect.
